SHADE-HOLDER.

Specification of Letters Patent.

Application med December 7, 1917. Serial No. 205,960.

. will grip and hold a shade securely and per-.

mit its convenient attachment and detachment, without the use of set screws, and which will securely grip a lamp socket without the use of clamping screws.

, With these and other objects in view, I have devised the novel shade holder of which the following description in connection with the accompanying drawing is a specification, reference characters being used to indicate the several parts.

Figure 1 is an elevation showing my novel shade holder in place upon a lamp socket and holding a shade,

Fig. 2 a perspective view of the shade holder detached, and

Figs. 3 and 4 are inverted plan views showing slightly variant forms of construction.

10 denotes the shade ring which is provided with a depending angle flan e 11 and one or more inwardly extending s ade supporting lugs 12. Thls ring is attached to an inner ring 13 by arms 14. Extending outward from ring 13 is an attaching collar 15, which is provided in its inner side with a circular groove 16, and is also provided with a plurality of slots 17 which cross the groove. The holder is blanked out and formed in one piece from resilient sheet metal. The effect of the slots in connection with the inner ring from which the collar projects is to adapt the collar to grip the lamp socket with a firm hold. It is of course well understood that all standard lamp sockets are provided near their lower end either with a single rib as 18 in Fig. 1, or with a plurality of smaller ribs, or with a rolled thread. In either event the resilient attaching collar, as constructed, will grip the socket firmly and securely.

' in Fig. 3, and one larger lug Cooperating with the inwardly extending shade supporting'lug or lugs, two as shown in Fig. 4, is

an inwardly gripping retaining spring 19, one end of which is either riveted or. soldered to the inner side of the shade ring, the free end curving inward and being provided with a finger piece 20 which extends outward through a slot 21 in the angle flange. This finger piece may be knurled as in Fig. 4 or curved as shown in Fig. 3. In this form, an outwardly extending fixed grip 22 may be provided, for convenience in moving the sprlng outward in connectingand disconnecting shade and holder.

The operation will be perfectly obvious from the drawing and description. In attaching a shade to the holder; the retaining spring is withdrawn from the gripping position by means of the finger piece, the attaching flange, indicated by23, of the shade is placed in engagement with the shade supporting lug or lugs, the opposite side of the attaching flange is raised ast the retaining spring and the spring 1s released. The spring when released, seats itself in the groove under the attaching flange and locks the shade securely in place. In attaching the shade holder to a lamp socket, the attaching collar is passed over the lower end of the lamp socket, tilted slightly and then pushed upward, the resilient collar yielding to receive the rib on the socket and gripping the rib firmly which retains the holder securely in place. To remove a shade it is simply necessary to relieve the grip of the retaining spring and tilt the shade slightly.

Having thus described my invention, claim:

A- shade holder of the kind described formed from a blank of metal to provide an inner and outer ring connected together by web' portions, the inner ring being stamped to provide an upstanding annular flange having a circumferential groove in its inner wall and vertical slots extending downwardly from the upper edge thereof and crossing said groove, the outer ring being stamped to provide a downwardly depending flange having an inwardly extending lug on the lower edge thereof, and a slot substantially opposite to said lug, an

es/apex;

elongated resilient member havin one end secured to the inner face of said flange and having its other end extending to a point substantially opposite said lug and normally lying spaced from the inner surface of the flange, and a finger piece secured to the free end of said resilient member and projecting outwardly through said slot whereby the free end of the resilient member may be brought to lie against the inner face of the 10 flange.v

In testimony whereof I afiix my signature.
